The Cincinnati Bengals confirmed Monday three hires to coach Zac Taylor's staff, including a key piece on the offensive side of operations.

Jemal Singleton will coach running backs, the position group that includes last season's leading AFC rusher in Joe Mixon. Singleton, 43, served in the same capacity for the Oakland Raiders in 2018 on staff alongside now-Bengals offensive coordinator Brian Callahan.

As previously reported, the Bengals confirmed Monday the hires of former University of Illinois staffer Joey Boese to a strength and conditioning role and former Moeller High School football coach Doug Rosfeld as director of coaching operations.

Both had prior work connections to Taylor.

Boese worked with Taylor at Texas A&M; Rosfeld spent a season with Taylor at UC.
